obscene
Explanation
The Joke
A woman tells her partner she made a "dirty movie" for him, with "things you probably never imagined I'd be open to." The man is excited and sits down to watch, only to exclaim "Mother of God" -- but not in the way one might expect. The twist comes in the third panel, where a friend asks the man if he always keeps that many browser tabs open. The "dirty" revelation was not sexual content but rather the horrifying number of open browser tabs visible on the computer screen.
That night, the man lies in bed saying he has "lost all respect for her." The punchline subverts the setup: instead of the implied sexual content being the shocking element, it is the woman's chaotic browser habits that constitute the truly "obscene" material.
The Humor
The comic works by exploiting the audience's assumption that "dirty movie" means pornographic content. Weinersmith sets up every expectation for a risque punchline, then pivots to something mundanely relatable -- the universal experience of being horrified by someone who keeps an absurd number of browser tabs open. The final panel, where the man has genuinely lost respect for her over this, elevates the joke by treating a minor digital habit as though it were a serious moral failing, reflecting how strongly some people feel about browser tab management.
